I want to reserve 4 seats for this lecture. It will be for Gary & Linda Amari and Giorgio & Stacy Allegro. I went to events@davincisanfrancisco, made my request there, however I was unable to ” send ” the email from that link. A little frustrating. I hope this is received by the right party and have secured reservations. Would you please email me back to confirm ?

Dear Gary Amari,
I apologize for the inconvenience and thank you for letting us know. There was a missing part at the address ” .com” and the RSVP did not go through. Paola Tonelli sent me your kind email and I put your names down in our list. Thank you again
Amelia
